like this? The second trenchcoat is just for style, trenchcoat, as the price of the actual jacket is well above 100 (closer to 500). But I bet that it is possible to find something similar for less
But really, My best advice would be to google around a bit, either by webpage or by picture, to find out if what you're looking for has a specific name. Or perhaps you will stumble upon something you like the looks of.
